High-density energy storage systems are batteries and long-duration storage designs built to hold more energy in less space
High-density energy storage systems are storage technologies designed to pack more usable energy into less space or weight. Here is what that means in practice, where these systems are used, and the trade-offs that matter most.
Premier Graphene wins first Mexican defense contract as graphene materials move into supply chain
Premier Graphene says it has secured its first defense contract in Mexico, marking a commercialization step for its graphene-based protective-wear technologies and opening a route into a tightly regulated military supply chain.
GMG says its graphene aluminium-ion battery now stores twice as much energy in latest test update
Graphene Manufacturing Group said on April 15, 2026, that its graphene aluminium-ion battery has reached 49 Wh/kg in a six-minute charging test, doubling the result it reported in December 2025 as it works toward customer testing and eventual commercial production.
First Graphene buys coatings assets to push graphene formulations into geotextiles
First Graphene said on April 28, 2026 that it agreed to buy the manufacturing, intellectual property and development assets of Ionic Industries and Imagine Intelligent Materials, a move aimed at giving it immediate access to revenue-generating graphene coatings formulations for geotextiles and environmental infrastructure.
